Answer:
The fluidity of the membrane is defined as the viscosity of the lipid bilayer, such that it can affect the inward and outward movement of the biomolecules. The correct option is Cholesterol. It affects fluidity by either decreasing or increasing. It is the most important factor for the regulation of fluidity.
Explanation:
Cholesterol affects the cell membrane's fluidity because these molecules are randomly distributed along the lipid bilayer. The cholesterol functions to hold the phospholipid together, such that it does not create large spaces and allow the movement of unwanted particles.
The cholesterol plays a crucial role in holding the phospholipids, as in the absence of cholesterols, lipid bilayer will separate and allow diffusion of unwanted molecules.
Glycoproteins are the molecules in which proteins having glycans are linked to amino acid side chains. These molecules play a crucial role in the recognition and adhesion of the cells.
Carbohydrates are linked to lipids, known as glycolipids, which are a vital part of cell membranes. These molecules function to address the loci but do not affect the fluidity of the cell membrane.
Fatty acids can be unsaturated or saturated, which consists of multiple or single bonds. These bonds result in fluidity.
